The Sector V Treehouse is the main headquarters for Sector V. It is built in a giant tree that grows from in the center of Numbuh 1's house (the tree is 560 years old, as Numbuh 2 notices in Operation: N.A.U.G.H.T.Y.), with various salvaged vehicles, like the bow of a ship, and the nose of a space shuttle integrated into the tree. The operatives live, sleep, eat and protect themselves from adult attacks in it. First seen in Operation: N.O.-P.O.W.U.H., the treehouse is normally attacked by villains day and night. It was later a villain, run by the treehouse computer in Operation: G.I.R.L.F.R.I.E.N.D.. Numbuh 2 mentioned being ready to upload the computer system into the rebuilt treehouse, jokingly saying how he hoped for different results, in Operation: T.R.E.A.T.Y.. Its final appearance was in Operation: I.N.T.E.R.V.I.E.W.S..
